automatic speed breaker detector

[dudul1]

It depends on the implementation of the speed breaker. Then can be knobs of less than a centimeter in the pavement, a bump over street of 10 centimeters, road signs, a display showing the current speed.

To consider all of them efficiently with a low error rate I suggest the following: Buy a commercial Matlab version, ask a student to sit on the passenger seat, offer Matlab as payment when the student mentions all speed breakers.

I'm not kidding. I'm physicist and this is seriously the best answer yet. When you want something more technical, please define the problem with any details. But I claim, that it is not useful from a global point of view to bother Matlab, when the job is trivial for humen. A two year old child will be better than the most intelligent Matlab program.
There is evidence to support the claim that speed-breakers can cause accidents and injury. When a vehicle approaches a speed-breaker at a speed greater than some threshold velocity, the risk of accident or injury is substantial. Speed-breakers are inconspicuous in low visibility conditions, like at night, or when there is fog, rain or snow. This problem is particularly acute in developing countries where speed-breakers don t always accompany warning signs. We propose an early warning system that uses a smartphone based application to alert the driver in advance when the vehicle is approaching a speed-breaker. In addition, the application constantly monitors the smartphone accelerometer to detect previously unknown speed-breakers. The proposed detection algorithm is easy to implement because it does not require accelerometer reorientation. This is one of the main contributions of our work since previous approaches have used expensive computations to reorient the accelerometer. The algorithm was evaluated using 678 Km of drive data, which involved 22 different drivers, 5 different types of vehicles (bus, auto rickshaw, cycle rickshaw, motorcycle, and car), and 4 smartphones. The results are very promising and can be further improved by aggregating detection reports from multiple smartphones.

dear sir.
myself krish,i'm studying engineering, i want to automatically detector of while i driving a car,i affected by unknown speed breaker so at that time i think about why? i inverttor it. so please requst to me. what are the materials need to make the this project because i am a computer science student so i cannot know the which type material need to it.

thanking you,
